It is this shared quality in the fleet-footed Arsenal attackers that gives top gun Walcott confidence that the pair of them together can become "a deadly force" in British football.

Sanchez recently swapped Barcelona for Arsenal in a £32 million deal earlier in the summer and has been training in North London, alongside Walcott, while a 20-man squad toured the East Coast of USA before a pre-season midweek trip to Bad Waltersdorf in Austria.

Walcott is currently concluding his rehabilitation from a complicated anterior cruciate ligament injury and has also been training in England, away from the rest of the squad.

The 25-year-old, who was responsible for a goal or an assist once every 85 minutes on average from the few games he played last season, is expected to return to first-team duty in the middle of September.

Sanchez, meanwhile, could make an appearance at the annual, four-team Emirates Cup friendly competition this weekend.
